CDC Streptococcus Laboratory
CDC’s Streptococcus Laboratory provides support for active population-based surveillance for invasive streptococcal disease, primarily caused by groups A and B streptococci and Streptococcus pneumoniae. It supports state and local health departments in the United States to characterize streptococcal isolates and is active in many international collaborations. The laboratory is a reference center for the identification and characterization of streptococci and other Gram-positive catalase-negative cocci.
Group A streptococci: Submit emm gene sequence to determine emm subtype of your strain.
There are many species and subspecies within the Streptococcus genus. CDC provides protocols for how to identify and differentiate species of streptococci.
